IMPROVEMENT IN REVGLVINGeEREECH FIRE=ARWIS.

Specifica-tion forming part of. Letters Patent No. @,2229, dated July 15, I1851.

Springfield, count-y of Hampden, State of Mas# sachusetts, have invented certain Improvements in the Construction ot Repeating FireyArms; and I do declare the following to be a full, clear, and exact description ot' the same, reference being made to the annexed drawings, forming part ofthe same, in which- Figure I is a view in perspective of my improveniente. Figs. II, III, 'and IV are parts in detail; and similar letters refer to similar parts throughout the tigures.

My invention relates to certain improvelnents in revolving arms, whereby asuperior method is attained ot' e'ecting the attaching and detaching of the barrels from their stocks.

My invention consists'in the engagement. and disengagement of the barrel from the stock. This is eected'with great facility in my improvements by merely slackening up a screw i-n the stock, attached near the end of the bnc-k strap ofthe barrel, when a quarter-revolution of the barrel will immediately release it from the stock. To accomplish this I aix a stud, c, having a square head, upon the stock. This stud is placed a little to one side of the central line or sight ofthe piece. In the side ot' the hacl5'brace-picce or strap, f, there is a.

notch cut to tit around the pin c, as clearly shown in Figs. I and IV. The top ot' the pin is Hush withV the surface of the brace, and has besides a hole drilled and tapped to receive a screw. This screw is seen in Fig. IV, and when screwed down its head, being larger than the top of the stud, presses upon the strap and prevents any movement of the barrel. The barrel outside ofthe revolving chamber is supported upon the end of the pin upon which they revolve by means of the hole drilled in )and III.

the lower end ot' the brace. In the old mode, to keep this part steady a hole is drilled through both the brace and pin and a key or screw inserted. My fastening dit'ers from this. The end ofthe shaft is cut with anotch, as seen in Fig. III at letter D. One side of the pin is then cut to form a flat surface extending from the notch out to the end, as seen at e, Figs. II A small pin is driven through the brace at e', Figs. I and II, and firmly riveted in it, so that it cannot, be moved. When the barrel is set in place this pin 'i lls the notch d, and consequently, together with the stud c, holds the barrel in place.

To remove the barrel the screw on c must be slightly slackened, as it is not necessary to take it ont, and the barrel being turned round until 'the little pin i comes opposite to the place where the notch is cut away at c, it can then be pulled ofi'. The stud c being a little to one side ofthe sight, the side of the strapf, in being turned slightly, rises up. The head ot' the screw therefore must be raised sufficiently tc allow the strap to pass from under. There fore, when screwed hard down, it prevents the barrel from turning or being misplaced.

I'Vhat I claim as of my own invention, and desire to secure by Letters Patent of the United States, is-

The arrangement for securing the barrel to the stock-viz., the combination ot the stud c with the notch inthe backxstramf, a'nd with the notch d and pin i, as described, the whole being constructed and operating substantially as set forth herein.
